Description

Technical Field

[0001] The utility model belongs to the technical field of alloy equipment, and in particular relates to a lead-based master alloy preparation device. Background Art

[0002] In the zinc electrowinning process, the quality of the anode plate has a significant impact on electrolysis efficiency and product quality. Currently, lead-based alloys are widely used as anode plate materials due to their excellent electrical conductivity and corrosion resistance. To improve the overall performance of the anode plate, elements such as silver, calcium, and strontium are often added to metallic lead to form lead-based alloys. The addition of these alloying elements can significantly improve the physical and chemical properties of the anode plate, thereby extending its service life and increasing electrolysis efficiency. However, in the production process of lead alloys, direct addition of these elements to the lead melt presents significant challenges due to the much greater specific gravity of lead than other alloying elements such as silver, calcium, and strontium. To overcome this challenge, existing techniques typically employ a method of first preparing an intermediate alloy and then adding it to the lead melt. While this method somewhat addresses the difficulty of adding alloying elements, the intermediate alloy preparation process still has several drawbacks.

[0003] Specifically, existing methods for preparing master alloys typically involve the following steps: first, melting a lead ingot to form molten lead; then, placing the alloying elements into a bell jar, which is then manually pressed into the molten lead. When large amounts of alloying elements are added, repeated manual pressing is required, which not only increases the operator's workload but also creates a harsh working environment. Furthermore, the high temperature and hazardous nature of the molten lead pose significant safety and occupational health risks to operators.

[0004] Therefore, in view of the above problems existing in the prior art, it is particularly important to develop a lead-based master alloy preparation device with compact structure, simple process, high production efficiency and degree of automation, and safety and reliability.
